Given:
The scale factor is 1:12.
Dimension of model = 32 cm
To find:
The actual dimension in m.
Solution:
Let x be the actual dimension.
The scale factor is 1:12 and the dimension of model is 32 cm.
[tex]\dfrac{1}{12}=\dfrac{32}{x}[/tex]
On cross multiplication, we get
[tex]x=32\times 12[/tex]
[tex]x=384\ cm[/tex]
[tex]x=3.84\ m[/tex] [tex][\because 1\ m=100\ cm][/tex]
Therefore, the actual dimension is 3.84 m.

A publisher sells 10 to the power of 6 copies of a new book.
Each book has 10 to the power of 2
pages.
How many pages total are there?
Answer:
100,000,000
Step-by-step explanation:
10^6= in this case, just add 5 zeros to the 10. each zero multiplies the number by 10
1000000 books
10^2 pages per book- 100 pages
1,000,000 x 100= 100,000,000

what's is m when u are looking for x or y intercept
Answer:
Slope.
Step-by-step explanation:
mx+b
Answer:
Slope
Step-by-step explanation:
The equation of lines are normally formatted in "slope-intercept form"
(y = mx + b)
The b in the equation would be the y-intercept of the line.
The m represents the slope.
The x and y can be replaced with any x and y value from the line (if necessary)

[PLATO] A circle is centered at the point (5, -4) and passes through the point (-3, 2).
The equation of this circle is (x + (1.) _______)² + (y+ (2.)_______ )² = (3.)_______
Answer:
1. -5
2. 4
3. 10
Step-by-step explanation:
this equation is in vertex form. Points 1 and 2 are the coordinates of the center of the circle (5 is the x coordinate, -4 is the y coordinate). To find the center of the circle, take the values of the given (5, -4) coordinate, and switch their sign (5 becomes -5, -4 becomes 4).
to find part 3, you will need to plug in the values of the second coordinate (-3, 2).
If you need to find the radius of (3), find the square root of whatever answer you got.
1. (x-5)^2 + (y+4)^2 = ___
2. (-3-5)^2 + (2+4)^2 = ____
3. (-8)^2 + (6)^2 =___
4. 64+36 = 100

(to find radius)
5. [tex]\sqrt{100} = 10\\[/tex]
the answer to 3 is 10
y
∝
√
x
If
y
=
45
when
x
=
81
find,
y
when
x
=
225
Answer:
y = 75
Step-by-step explanation:
Given that:
y [tex]\alpha[/tex] [tex]\sqrt{x}[/tex]
⇒ y = k[tex]\sqrt{x}[/tex]
where k is the constant of proportionality.
When y = 45, x = 81, then;
45 = k[tex]\sqrt{81}[/tex]
45 = 9 k
k = [tex]\frac{45}{9}[/tex]
= 5
k = 5
So that,
y = 5[tex]\sqrt{x}[/tex]
the value of y when x = 225 is;
y = 5[tex]\sqrt{x}[/tex]
= 5 x [tex]\sqrt{225}[/tex]
= 5 x 15
y = 75

which is the best prediction of what the population of San Francisco will be in 2015?
Answer:
initial pop'n=776733
growth rate=15%
time= 15years
Then,
Pt= P(1+G/100)^t

In a maths class the girl to boy is 7:5 If there are 20 boys how many girls are in the class
Answer:
Let the total no of girls be x
the number of boys=7:5
total no of students =20
now,
no of girls =7/5=x/20
or, 20*7=5x
or 140=5x
or,x=140/5=28
therefore the number of girls =28

Given isosceles right triangle CDE with m∠D = 90, sin C = sin D
Answer:True
Step-by-step explanation:
Given
[tex]\angle D=90^{\circ}[/tex]
For isosceles triangle , CD=DE (x=y)
from figure,
[tex]\sin C=\dfrac{y}{H}\\\\\sin D=\dfrac{x}{H}\\\\\text{CD=DE}\\\\\therefore \sin C=\sin D=\dfrac{x}{H}=\dfrac{y}{H}[/tex]
Thus, the given statement is true
